I Red Bluff Dam and Reservoir was created to impound water for irrigation and for hydroelectric power. In 1933 the construction of the Red Bluff Dam and Reservoir was approved as a project of the U.S. Public Works Administration and Construction would begin in November of 1934. The Red Bluff Dam and Reservoir was completed in September of 1936. The reservoir would have a capacity of 310,000 acre-feet of water. The dam is 9,230 feet long, maximum height of about 106 feet and top width of 25 feet. The reservoir was built with three main sections: The main embankment across the river, An emergency fixed- crest spillway lying west of the main dam, and a concrete gate controlled spillway located in a cut west of the emergency spillway. ​​In June 1937 floods filled the reservoir and has since been used for supplying irrigation water to seven water improvement and irrigation districts downstream.
